Notes

Example—
The transformer has a nominal current of 10A with an inrush current of 18 times the nominal current. So, the contactor must have an
AC-3 current of 18/6 x 10A = 30A. Using an XTCE032C (32A AC-3) contactor is recommended.

For 225–275A, use 2X 70 mm

wire.

At maximum permissible ambient temperature.
